Important Bug Fix, Trilobot memory, Trilobot communication

A pretty important bug that was causing trilobot meta-programs longer than 2 nodes deep to return undefined values was fixed.

New meta-program operations were added to the Trilobots' minds, allowing them to store and load internal variables, send and retrieve global variables to use as messages to other trilobots, and operations similar to assembly-style languages' "increment/decrement and branch if equal" operations.

There's also an operation that will run the left branch once, and the right branch thereafter, which could be used to initialize variables.
